PROBLEM TO BE SOLVED: To provide a flush toilet bowl system capable of discharging waste water with a smaller amount of flushing water. SOLUTION: In this waste removable system, a water supply manifold 40 comprising a tertiary outlet nozzle having a main outlet nozzle 42, a secondary outlet nozzle, and a large number of holes 48 is formed at the upper edge of the bowl part of a toilet bowl 28 for concentrating the flushing water to an arresting part 51. A changing part 58c having a generally halved cross sectional area is formed on the inlet side of the arresting part 51 of the toilet bowl 22 for increasing the speed of the flushing water passing through the arresting part. The cross sectional shape of the drain pipe connected to the downstream side of a flushing outlet 50 is oval in which the ratio of the height to width is 1.4 to 1-1.5 to 1 and the ratio of the upper part radius to the lower part radius is 3 to 1. Consequently, excreta can be surely flushed even if the flow of water is small or large. COPYRIGHT: (C)2009,JPO&INPIT
